Generally, discharge containers are widely used for discharging liquid contents of cleaning products such as shampoo, rinse, etc., cosmetics and the like. An example of a dispensing device used in such a cosmetics discharge container is shown in FIG. 1. The dispensing device for a cosmetics container shown in FIG. 1 (Korean Utility-model Application Publication No. 20-472459 published on Apr. 29, 2014) is coupled to an upper part of the cosmetics container in which liquid cosmetics are contained and discharges a certain amount of cosmetics, and is provided with a button 10 provided on an upper side of the dispensing device and a nozzle 11 coupled to a front surface of the button 10. A shaft 20 extending vertically is coupled to a lower side of the button 10, and the shaft 20 is supported by a spring 21. The button 10 is pressed downward and inserted into a cover 30 coupled to an opening of the cosmetic container. A fixed cap 40 is coupled to the inside of the cover 30. The lower end of the shaft 20 is inserted into the upper side of the fixed cap 40 and a stem 50 coupled with the piston 60 is inserted into the lower side of the fixed cap 40, and is inserted into the inner side of the shaft 20. A transfer space 51 is formed in the inside of the stem 50. An upper side of the transfer space 51 is opened and contents are transferred through the transfer space 51. A plurality of throughholes 52 communicating with the transfer space 51 are formed radially on the lower outer circumferential surface of the stem 50. Meanwhile, a housing 80 is provided in the lower side of the fixed cap 40 and a fixing ring 31 coupled to an outer circumferential surface of the housing 80 is fixed to the inner side of the cover 30. The shaft 20, the stem 50, and the piston 60 are configured to move up and down in the inner side of the housing 80. In addition, the inside of the housing 80 is provided with an opening and closing member 70 which can move up and down. A space 71 opened upward is formed inside the opening and closing member 70. A hemispherical head 72 is formed on the lower side of the opening and closing member 70 and a plurality of wings 73 are formed radially on the outer circumferential surface of the opening and closing member 70. An air hole 81 is formed on the upper outer circumferential surface of the housing 80. A step 82 is formed on the inner lower end of the housing 80 and a suction hole 83 is formed on the lower side of the step 82. The wings 73 of the opening and closing member 70 serve as a stopper which is brought into close contact with the step 82 so that the wings 73 can no longer move upward. The suction hole 83 is opened or closed since the head 72 is spaced apart from or comes into close contact with the suction hole 83. A contact portion 84 is formed on the inner circumferential surface of the upper end portion of the suction hole 83 so as to be in close contact with the head 72. The contact portion 84 is formed in a circular arc shape corresponding to the hemispherical head 72. When the button 10 is pressed downward in order to discharge the contents in the cosmetic container dispenser configured as described above, the stem 50 and the piston 60 descend together and the outside air is sucked toward the inside of the housing 80 through the air hole 81. While the contents filled between the stem 50 and the opening and closing member 70 are compressed, the opening and closing member 70 is lowered and the head 72 seals the suction hole 83. Here, as the stem 50 descends, a pressure is generated inside the housing 80 so that the piston 60 rises up. As a result, the contents are sucked into the transfer space 51 through the opened throughholes 52, and discharged through the nozzle 11.
However, such a conventional cosmetics discharge device has a disadvantage in that the manufacturing cost is increased due to a large number of components and a complicated structure, and thus the cost of the finished product filled with the contents of the cosmetics is considerably high. In addition, the cosmetic liquid which is filled in the lower part of the container is sucked up and discharged. However, the contents located on the bottom of the container below an infusion tube for sucking the contents remain, and the contents are not completely exhausted.
